SPINNING-MACHINE.

SPECIFICATIONforming part of Letters Patent No. 246,469, dated August30, 1881.

Application filed April 4, 1881. (No model.)

To ali whom it may concern:

Be it known that I, RICHARD B. DALY, of Newton Upper Falls, county ofMiddlesex, Stat-e of Massachusetts, have invented a new and usefulImprovementin Spinning-Machines, of which the following description, inconnection with the accompanying drawings, is a specification.

This invention in vspinning-machines is an improvement on that class ofspinning-machines known as speeders.77

y In this my invention the spindle, which does not traverse as itrotates, is made quite short, it extending from the step-rail up throughthe lier-rail and through the bottom of the ienjust far enough to enableits upper` end to enter the bobbin guide-rod above the head of a sleeve,which, surrounding the spindle, engages the lower end of the bobbin justabove the bot-tom of the iiier. This bobbin guiderod, which receives andholds the bobbin during its rotation by the head of the said sleevedriven by the spindle, is loosely connected with the yoke at the top ofthe hier, so that the said rod may be raised or moved longitudi- `iiallyfar enough t0 remove the lower hollow end\of the rod from or cause it toengage the reducefLupper end ofthe spindle. When the rod and spindle aredisengaged the rod may be swung outward to remove a bobbin from the rodor put one on it; but when spinning,` is being done the rod and spindleare engaged, and the rod `serves both as a continuation of the spindleand as the center support for the bobbin during its rotation, the rod,as herein shown,I rotating with the spindle by means of the taper titbetween the upper end ofthe spindle and the rod 5 but it will beunderstood that the fit between the spindle and rod may be such as toleave the rod substantially at rest.

Figure lrepresents, in front elevation, asuflicient portion of aspinning-frame to illustrate my invention, some of the parts beingbroken out to better illustrate their construction; Fig. 2, a partialside elevation, showing the guiderod swung out from between theHier-arms as it will be when dofng. Fig. 3 is an enlarged detail of thelower end ot' the flier, guide-rod, bobbin-tlier gear, its support or.bearing, and

the upper end of the spindle and sleeve; and Fig. 4 is a cross-sectionof the sleeve and spindle on the line x x, Fig. 3.

In speeders as heretofore made, so far as I am aware, the gear whichdrives the hier has had its support in a dier-rail, the spindle has beenguided in a spindle-rail below the Hierrail, the gear for driving thespindle being located at the spindle-rail, and below these rails thelower end of the spindle has been supported in a traversing step-rail,thus requiring a considerable length ot' spindle below the bottom of thetlier. By my construction I have been enabled to materially shorten thelength ofthe spindle below the bottom ot' the flier, and am thereforeenabled to lower the iiier.

The spindle a has its lower end fitted to a step, a2, in the step-raila", set preferably on or close to the mill-licor. and above the steprailthe spindle has a gear, a', connected with it, which is driven by thegear d3 on a stud having at its upper end a bevel-gear, a", driven froma bevel-gear, a5, on a horizontal shaft, a6, extended lengthwise ot' theframe either outside or inside the spindles, such shaft d6 and itsattached bevel-gears a5 being now commonly used in Speeder-frames.

The rail b receives the bolster b for the neck b2 ot' the dier-gear b3,the bottom-c ot' the ier d being connected with the top part, b4, of theflier-gear, so as to be driven by it. The hollow neck of the Hier-gearreceives through it the sleeve e, having a head and collar, c, providedwith a bobbin-drivingdog or stud, e2, ot' any usual construction. Thelower end of this sleeve is supported upon a projection ot' thetraverse-rail f, arranged at the rear side of the row of spindles of theframe, and operated in the usual manner, the traverse-rail being,however, in my plan located between the step and iiier rails. The sleevee is connected with the spindle by a spline, a, so as to be rotated bybut yet slide on the spindle. The spindle has its lower end or stepbearing in a tixed .step-rail, and the sleeve is raised and lowered onthe spindle by the traverse-rail, the head e of the sleeve, during itsrotation, being traversed up and down on the guide-rod g, the dogengaging and rotating the bobbin t for spinning. The upper end of thespindle, projected just above the bottom of the flier, and above thehead e when the sleeve is fully depressed, is, as herein shown, taperedor reduced in diameterto itaholemadeinthelower end of the guide-rod g,the latter, when upon the spindle, as in Fig. l, forming practically acontinuation of the said spindle.

rlhe upper end of the guide-rod gis provided with a head, g', and areduced portion, g2, below it, the head g', when in the socket made forits reception in the part h of the dier-yoke h2, serving to support therod so firmly that it cannot move laterally at top; but when theguide-rod is lifted, as in Fig. 2, the head g is removed from the saidreceiving-socket, bringing the reduced portion g2 of the rod g oppositethe part h ot' the yoke, so that the guiderod, its lower end being atsuch time lifted above and disengaged from the top of the spindle, maybe turned or swung out from between the arms ofthe flier, as in Fig. 2,to dott the bobbin fi, which iu Fig. 1 is shown in elevation and whichmay be otan y usual construetion.

The hollow nose 7b3 of the flier, above the yoke h2, is steadied in theusual flier-plate, h4.

The Hier-gear b3 is driven by a shaft, Z., like shaft a, having a systemof bevel-gears, l, like gear a5, each gear l engaging a bevel-gear, Z2,secured to the neck of the gear Z3, which engages and drives theflier-gear.

In my improved construction, with the rails located as described, thetraverse-rail being between the dier-rail and the steprail, I am enabledin practice to reduce the length of the spindle below thetlier-rail-say, in a twelveinch traverse spindle, atleast nineinches-thus enabling the hier and usual roller-beams above 4o it to becorrespondingly lowered, which is ot' great importance, as it enablesthe bobbin and usual delivery-rolls to be so lowered as to greatlyfacilitate clotting and enable the spindles and fliers to be run moresteadily.

I claiml. The shortened spindle and fixed step-rail for it and the flierand Hier-gear and rail to support it, combined with the bobbin-engagingsleeve litted to the spindle and extended through the flier-gear, andwith the tra-verserail and suitable means to operate it and rotate thespindle, substantially as described.

2. The shortened spindle, the fixed rail to support its lower end, thesleeve fitted to the spindle, as described, and provided with abobbin-engaging head, and suitable means to rotate the spindle, combinedwith the lier and the loosely-connected bobbin guide-rod, adapted to titthe upper end of the spindle to retain the bobbin in place or to bedisengaged from the spindle and swung out for dofting the bobbin,substantially as described.

3. The flier and its yoke and portion h,l1aving a socket therein,combined with the bobbin guide-rod having a head, and reduced indiameter below the said head to permit the head to belifted from thesocket and the guiderod to be swung out ot' the flier, substantially asdescribed.

In testimony whereofl have signed my name to this specification in thepresence ot' two subscribing witnesses.
